- Lemon zest gets mixed into the muffin batter for an infused lemon flavor in every bite.
- Adding vanilla extract to these lemon muffins gives them just the right amount of sweetness!
- Vegetable oil prevents the zucchini lemon muffins from drying out for several days. Any neutral oil will work. You can even use melted butter, but the flavor and texture may differ slightly.
- Baking powder and baking soda work together to give them the perfect rise and fluffiness.

Substitutions & Variations

How to Make Lemon Zucchini Muffins
Quick Recipe Video
Step by Step Instructions
Step 1: In a large bowl, whisk together the flour, baking powder, baking soda, and salt.
Step 2: In a medium bowl, whisk the oil, granulated sugar, lemon zest, eggs, vanilla extract, lemon kefir, and shredded zucchini until fully combined.
Step 3: Fold the wet ingredients into the dry mixture just until the flour streaks disappear.
Step 4: Scoop the batter evenly into 12 muffin liners. Bake at 425°F for 5 minutes, then reduce the heat to 350°F until a toothpick comes out clean (about 15-20 minutes total).
Optional Lemon Icing
Whisk together the powdered sugar, lemon zest, lemon juice, and milk until smooth. Add more or less milk to meet your icing consistency preference!
Once the muffins have cooled, drizzle the lemon icing on top of them. You can also just dip the tops into it!
Expert Baking Tips
- Use a food scale to weigh the flour in grams for the most accurate measurement. Using measuring cups can add too much flour, yielding dry muffins.
- Don't overmix the batter or the muffins can become tough instead of fluffly. Stop mixing as soon as you no longer see streaks of flour.
- Make sure to start baking your muffins at 425°F to get the tops to rise like bakery-style muffins. I highly recommend using an oven thermometer to make sure your temperature is accurate. Make sure you leave the oven door closed while reducing the temperature!
Common Questions
No. Blotting or squeezing the zucchini removes the moisture which is needed in the muffin batter.
While both are vegetables with high water content, they actually are quite different. Zucchini has a mild, sweet flavor and softer flesh, making it great for baking. Cucumbers are much crisper with a more distinct, vegetal taste.
Lemon zest is the most outer part of the lemon peel that's packed with natural oils and flavor. Use a fine microplane to zest the lemons before juicing them.
